Gmail - easy fix for duplicate sent mails No longer have to use different accounts for incoming/outgoing servers in order to eliminate the duplicates! (Might just be a solution for IMAP) Let's get it out of the way first: from your phone -> Gmail -> Menu -> Tools -> Options -> B Sending -> UNcheck "Save copies of sent items" -> Done! Here's what i think is going on: When you send email via gmail on your phone (not via web; but by the email client set up as POP or IMAP), and you have that "Save copies of sent items" enabled, google/gmail will automatically add a "Sent" Label to that email. The recipient does not see the duplicate but you do because the actual email that you send gets inserted into the conversation as well as the item with the "Sent" label. (look further, i think the recipient does see the duplicates depending on email client.) Now, unchecking that "Save copies of sent items" disables google/gmail from automatically creating/adding that label and, therefore, does not add it to the conversation. You might think "but i want a copy of my sent email". No worries...a copy is in your "Sent Mail" folder (where you see "Inbox", "Starred", "Chats", "Sent Mail", "Drafts", etc.) here's a pic to kinda illustrate: I have mine set for IMAP and have done several test sends back and forth with and without the option checked. I was able to replicate the problem and the fix consistently. Please let me know how it works for you, especially if you have it setup for POP, that would be much appreciated. *Edit* upon further testing, having set up a POP account, i think it only works for IMAP setups.
